资源简介：
Tungsten concentrations in aqueous fluids in equilibrium with tungsten oxides and synthetic scheelite (CaWO3) at pressures up to 50 MPa and temperatures up to 400°C. Further, EXAFS and XANES data for constraining the W species up to 400°C and up to 60 MPa. The dataset consists of i) experimentally determined W concentrations at pressure and temperature in H2O, HCl-solutions and NaCl-solutions; the concentration were determined by the x-ray absorption technique in situ at pressure and temperature; ii) EXAFS and XANES spectra and associated fit results for constraining the W-species in the fluid; iii) results of thermodynamic modelling based on thermodynamic properties derived from the W solubility data and data from the literature.
